EXTINGUISHING ATTACHMENT FOR LAMPBURNERS.,

Specification of Letters Patent. Patented Feb, 22 1921,

Application filed September 8, 1920. Serial No. 408,934.

To all to [0772 it may concern Be it known that I, FRANK Riioz, citizenof Hungary, residing at Coatesville, in the county of Chester and Stateof Pennsylvania, have invented certain new and useful Improvements inExtinguishing Attachments for Lamp-Burners, of which the fol lowing is aspecification.

This invention relates generally to lamp burners, having more particularreference to an attachment adapted to be applied to the burner wherebythe latter may be extinguished and the smoke from the extinguished wickprevented from escaping.

The invention has for an object to provide a novel and simple attachmentfor a lamp burner which operates as above set forth.

For further comprehension of the invention, and of the objects andadvantages thereof, reference will be had to the following descriptionand accompanying drawings, and to the appended claims in which thevarious novel features of the invention are more particularly set forth.

Figure 1 of the drawings is a horizontal sectional view of a lamp burnerhaving the invention applied thereto, this view being taken on the line11 of Fig. 2.

Fig. 2 is a vertical sectional view on the line 2-2 of Fig. 1. v

Fig. 3 is a vertical sectional view on the line 8-3 of Fig. 2, this viewbeing taken at right angles to Fig. 2.

My improved attachment may be applied to any burner of ordinaryconstruction, the numeral 10 indicating the base of the burner, 11 thewiclrtube, 12 the wick feed rod and 13 the dome, while 14 indicates theusual horizontal top member of the base. A portion of the bowl of a lampis indicated in dot and dash lines at 15, and of the chimney at 16.

My improved attachment comprises a pair of complementary hood elementswhich are arranged to jointly fold over the wick tube 11 while closelyengaging the sides of the latter at their lower ends to prevent escapeof the smoke.

Each of these hood elements comprises a flat shutter 18 which is of alength as great as the width of the wick tube and is hinged at one endto the latter as at 19 a short distance below the upper end thereof. Thefree ends or edges of these shutters may be convexly curved as shown inFig. 1 wh1le a laterally projecting flange 20 is formed oneach of theshutters which extends around this concavely curved .edge and theadjacent sides of the shutter. It is'to be understood that the parts areso proportioned that when the shutters are thrown upward to I theposition indicated in dot and dash lines head 26, these T-heads beingfixed on the upperends of a pair of arms 27 which are herein the form ofangular extensions from a pair of rods 28 which extend along onoppositesides of the wick feed rod 12 and are rotatably supported in brackets 29carried by the latter. These rods 28 have handles 30 fixed to theirouter ends. It is to be understood of course that the horizontalpartition member 14 will be suitably slotted to permit of movement ofthe arms 27.

It is believed that the manner of operation of my improved attachmentwill be apparent from the above description. By pressing upon thehandles 80 to swing them toward one another the arms 27 will becorrespondingly swung, and since the heads 26 on the ends of these armsnormally engage the outer ends of the guides 25, the inward movement ofthe arms will cause the shutters 18 to be swung up into operativeposition. The flanges 20 on the shutters preferably engage each otherwith sufficient frictional force to retain the shutters in theiroperative position until the handles 30 are again pushed apart, so thatthe end of the wick may remain inclosed to prevent escape of the smoke.

Having thus described my invention what I claim as new and desire toprotect by Letters Patent of the United States is as follows:

1. A device of the class described comprising, in combination with thewick tube of a burner, a pair of shutters hinged to said wick tube onopposite sides thereof and having angular marginal flanges adapted toengage within each other, and means for swinging said shutters upontheir hinges,

said means including T-guides formed on the said shutters, and rotatablearms having T-heads slidably engaging in the said guides.

2. A device of the class described comprising, in combination with theWick tube of a burner, a pair of shutters hinged to said wick tube onopposite sides thereof and having angular marginal flanges adapted toengage within each other, and means for swinging said shutters upontheir hinges, said means including a pair of T-guides formed on thebacks of said shutters, heads engaging freely in said guides, arms onwhich said heads are mounted rods on which said arms are fixed, andhandles on said rods for rotating the same.

3. A device of the class described comprising, in combination with theWick tube of a burner, a pair of shutters hinged to said wick tube onopposite sides thereof and having angular marginal flanges adapted toengage Within each other, and means for swinging said shutters upontheir hinges, said means including a pair of T-guides formed on thebacks of said shutters, heads engaging freely in said guides, arms onwhich said heads are mounted rods on which said arms are fixed, andhandles 011 said rods for rotating the same, said rods extending alongopposite sides and being supported by, the Wick feed rod of the burner.

In testimony whereof I have affixed my signature.

FRANK RAOZ.
